WSAEADDRINUSE (10048) Address already in use. In this case, it might be possible to check the count of TCP RST packets received, or ICMP Port Unreachable packets. User suggestions: Did you enter a destination hostname? the HTTP, HTTPS, FTP diagnostic is also in the red. http://nbxcorp.com/socket-error/winsock-2-error.html

The explanation is simple and obvious: in order to connect to or send to a destination address, you need to provide the destination address. Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations. If an application sends a UDP packet to a host/port that does not have a datagram socket "listening," the network system may respond by sending back an ICMP Port Unreachable packet Windows Sockets only allows a single blocking operation—per- task or thread—to be outstanding, and if any other function call is made (whether or not it references that or any other socket)

WSAEADDRNOTAVAIL (10049) Can't assign requested address Normally results from an attempt to create a socket with an address not on this machine. Sure enough, when I downloaded and ran another 16-bit app, it got the same error as I've been seeing.

This error occurs when the sin_port value is zero in a sockaddr_in structure for connect() or sendto().
